Abstract (en)
[origin: US2012216923A1] The present invention provides a manufacturing apparatus of a hot-rolled steel sheet capable of cooling control of a steel sheet even when disposing a cooling device capable of cooling from inside a finishing mill. The manufacturing apparatus of a hot-rolled steel sheet comprises: an immediate rapid-cooling device capable of spraying cooling water, at least a part thereof being disposed inside a final stand in the row of hot finishing mills; a device for measuring a temperature on an entry side of a final stand; a device for measuring a steel sheet passing speed; a device for predicting a rapid-cooling stopping temperature which calculates a predicted rapid-cooling stopping temperature; and an immediate rapid-cooling control device which corrects the water supply volume or water supply pressure of the immediate rapid-cooling device such that the predicted rapid-cooling stopping temperature matches a targeted rapid-cooling stopping temperature.
